摘要: 将经过筛选和驯化得到的高效复合微生物菌群固定在竹炭颗粒的表面和孔隙内部,制备得到固定化微生物竹炭。采用装填固定化微生物竹炭的接触塔对废水中的主要污染物进行降解。结果表明: 采用粒径为20mm的颗粒状固定化微生物竹炭,在水力停留时间为60min的工况下,对废水中的化学需氧量(COD)、氨氮、总磷、色度、浊度的去除率分别达到75%、 40%、20%、50%和50%,对COD、氨氮、总磷的最大去除负荷分别为170、30和18g/(m3·h),单位质量竹炭固定的微生物个数为122×1010个/g。

Abstract: The high degradation capacity microorganism was immobilized on the speciallyprepared bamboo charcoal particulate with an average diameter of 20mm, and a laboratoryscale contactoxidation filter packed with this complex was employed to biodegrade the typical contaminants in wastewater. The results showed that under the hydraulic retention time (HRT) of 60min, the elimination efficiency of COD, NH3-N, TP, chroma and turbidity reached 75%, 40%, 20%, 50%, 50%, and the maximum elimination loadings of COD, NH3-N, TP were 170g/(m3·h), 30g/(m3·h), 1.8g/(m3·h), respectively. The strain number of unit mass bamboo charcoal was 1.22×1010per gram.
